The wheel 3 has faces 10,11, which between it and the wheel and resulting m turned or cut around the circumference thereof. By reason of this construction the friction surface of the wheel is greatly increased and the inflow and outflow of steam is increased without enlarging the wheel or easing, resulting in the power of the engine being increased. Wlth the wheel shown in 1 1g. 4 a special form of abutment having teeth 19 entering in the grooves of the wheel must be used. This abutment'is made in the form of a comb to be slipped in place in a groove in the stationary abutment 4c and secured therein, as shown in Fig. 1. Obviously, the construction and arrangements of parts heretofore described admits of considerable modification without departing from my invention and I do not wish to be limited to the details thereof. Thus, while the drawings illustrate a simple singlestage expansion engine, it is evident that the engine may be compounded. It is also evident that it may be operated with other motive fluids besides steam, air, gas and water.

What I claim is: a

1. A fluid friction motor comprising a cylindrical casing, a chamber located on said casing, a port leading into said casing and a port leading out of said casing, a valve for controlling said ports, a wheel having a chambered face rotatably mounted on a 40 shaft within said casing, a channel between the face of said wheel. and said casing, said. channel extending nearly around the face of said wheel, an abutment located between the inlet and outlet ports of said casing, saidabutment bearing upon the face of said wheel, and means for reversing the direction of flow of the "fluid through said channel.

2. A fluid friction motor comprising a casing having inlet and outlet passages, communicating chambers connected therewith, ports leading from one of said chambers to the interior of'said casing, a valve cutting off communication between said chambers 55 and controlling said ports and adapted to connect reversibly said ports with chambers, a power wheel within said casing having a grooved periphery, said power wheel being spaced from the inner wall of said casing to form' a circumferential passage extending nearly around the power wheel and connecting said ports, and an abutment'on said casing between said ports closing the ends of said circumferential passage.
